Course Introduction

Offered by ZeroTurnaround in Spring semester 2017. The course will be taught in English.

Course code: ITI8905
Credits: 3 EAP
Time: Lectures on Mondays 12:00-13:30. First meeting on January 30.
Place: ICT-315 (ICT building is at Akadeemia tee 15a)

The course is targeted to students who (think they) already know Java. It is not a beginner's course!

NB! The number of places is limited to 40! Sign up ASAP! When we cannot find any evidence of you having taken some Java courses in the past, we may vacate the place to other students.

Students from TUT should register in ÕIS (registration will be opened on ~~January 11~~ January 30). Students from Tallinn University and IT College, who are interested in taking the course should send an e-mail to Siiri Taveter (siiri.taveter@ttu.ee) mentioning ITI8905 in the subject line.

Final Grade

Your final grade will consist of:

50% Homework
50% Exam

Homework

There are 14 homework assignments total for Lectures 1-14. The last lecture (lecture 15) will not have a homework assignment. Each assignment submission will be scored between 0.0 - 1.0. For a perfect score for homeworks you need at least 12 points out of the 14. So there is some buffer if you happen to miss a homework or if you didn't get a great score for each of them. For those of you that happen to get more than 12 points, we will make your life easier on the exam :).

Homework assignments for the lectures will be given out at the end of each lecture (Monday) and each one, except for the first one, will need to be submitted by Sunday 23:59 EEST same week. This means you have 6 days for solving the homework and submitting it to us for grading. Don't be late - if you are late then you'll get 0 points and we won't even look at it!

No cheating:

Copying solutions from a friend is forbidden - if we see two identical submissions, they both get a 0.
Copying solutions from StackOverflow is forbidden - its okay to look at solutions for ideas, but don't blatantly copy.

Use the Java Standard Library unless homework assignment itself uses some other libraries

Exam

The exam will be:

60% written (multiple-choice questions)
40% oral (2+1 questions)
NB! Prerequisite: must get at least 6 points for Homework

- General feedback:
  - Very many of you print the stacktrace before throwing a new exception or returning null.The convention in the industry is to have exception logging (print it out in some sort) at one single location at some higher part of the calling chain. In your catch sections I would either handle the exception (some logic) or re throw.
  - Make sure you close your streams! Classloaders are usually quite hot, meaning that they process a ton of files. If you happen to leak a handle each time then the leak can be substantial! Don’t forget to close them in the finally block or using the more convenient try-with-resources approach.
  - Test your submission before you send them in! Out of the 22 submissions 4 threw an exception with the supplied input files.
